However, it is not known whether TGF-β1 is also elevated in the blood of patients with tricuspid aortic valve and aortic dilatation. We analysed the plasma levels of TGF-β1 in 52 patients with tricuspid or bicuspid aortic valve and with normal or dilated ascending aorta who underwent cardiac surgery in our hospital. TGF-β1 blood level was significantly increased two-fold in patients with tricuspid aortic valve and dilated aorta compared to patients with tricuspid aortic valve and normal aorta. Our results suggest that TGF-β1 blood levels may serve as a prognostic biomarker for patients with syndromic and non-syndromic thoracic aortic aneurysm. Further studies with larger cohorts of patients should be performed to confirm these results.enAortic dilatationBicuspid aortic valveBiomarkerTGF-βAgedAortic Aneurysm, thoracicAortic ValveBicuspid aortic valve diseaseBiomarkersCardiac surgical proceduresFemaleHeart valve diseasesHumansMaleMiddle agedPrognosisTransforming growth factor beta1research article28666329open accessAneurisma de la aorta torácicaBiomarcadoresEnfermedad de la válvula aórtica bicúspideEnfermedades de las válvulas cardíacasFactor de crecimiento transformador beta1Procedimientos quirúrgicos cardíacosVálvula aórtica10.1093/icvts/ivx1531569-9285https://academic.oup.com/icvts/article-pdf/25/4/571/20146921/ivx153.pdf
